Japan is set to open world’s first 3D-printed train station, marking a major milestone in railway construction. The new Hatsushima Station, part of the Kisei Line in Arita, Wakayama Prefecture, will replace an aging wooden structure with a modern, single-story building made of reinforced concrete.
West Japan Railway Company (JR West), along with JR West Innovations Co., Ltd. and Serendix Inc., is leading this groundbreaking project. It is is the world’s first train station built using 3D printing technology, company says in the press release.
Faster construction with 3D printing
The new Hatsushima Station will measure just under 10 square meters, with a height of 2.6 meters, a width of 6.3 meters, and a depth of 2.1 meters. The structure will be created using a high-tech 3D printer, which will print the exterior parts, including the foundation. Once printed, the parts will be reinforced and filled with concrete before being transported to the station site.
On-site, workers will use a crane to assemble and join the components. The entire process—from dismantling the old station to completing the new one—will take just six hours. Construction will begin after the last train departs on March 25 and finish before the first train arrives the next morning.
3D-printed architecture continues to go from strength to strength, with all kinds of projects now being created with the burgeoning technology, including a Walmart, housing, and even a data center.

This method offers a major advantage over traditional steel and reinforced concrete construction, which can take weeks or even months. The streamlined approach will help reduce labor demands, which is becoming increasingly important due to Japan’s workforce shortage.
Stronger and more flexible design
The new station will be made of reinforced concrete, ensuring greater durability and resistance to corrosion. Since 3D printing does not require traditional formwork—wooden or metal frames used to shape poured concrete—designers have more freedom in shaping the building. This allows for creative and customized station designs beyond the usual box-like structures.
The exterior of Hatsushima Station will feature images of Arita City’s famous oranges and tachiuo fish, adding a local touch to the design. The concept was developed by Nouveau First Class Architect Office, Inc., in collaboration with JR West’s Osaka First Class Architect Office. Structural design was overseen by KAP First Class Architect Office.
Testing for future expansion
JR West selected Hatsushima Station for this project due to its coastal location. The company plans to monitor how well the structure withstands the salty air, which can cause damage over time.
In addition, the project will assess overall construction and maintenance costs. If successful, similar 3D-printed stations could be introduced across Japan.
Beyond this specific project, JR West aims to use advanced technology to modernize railway infrastructure. The company envisions a future where sustainable, cost-effective, and eco-friendly train stations become the norm.
